Get your free estimateFast, Reliable Home Addition Contractor Across Greatwood
Most full-size additions in Greatwood run $160,000 – $320,000 depending on square footage, and the defining variable here isn’t lumber or labor. It’s whether your street’s Architectural Review Committee approves the design on the first submittal or kicks it back twice. Sutton ADU Houston handles the entire packet for you, including the finish samples and elevation drawings Greatwood committees actually want to see. Call (940) 242-3207 and we’ll walk you through what your specific block will likely approve before you spend a dime on design.
We know Greatwood’s subdivisions street by street. Canyon Gate reads differently than Lakemont. The same rear-yard addition that clears one committee gets flagged on the next block for a roofline or driveway-width issue. Our Greatwood crews file pre-application HOA reviews three weeks before any demolition, so the review clock runs alongside our material lead times instead of stacking on top of them.
Every Sutton project in Greatwood starts with a written price before work begins. No change orders slipped into the invoice. No crew you didn’t approve showing up at your door. You get a name, a photo, and a badge before anyone sets foot on your property. That’s the Threshold Standard, and it’s the only way we build here.
Why Sutton ADU Houston Is Greatwood’s Preferred Home Addition Contractor Company
Greatwood homeowners don’t ask us for the cheapest bid. They ask who’s coming to their property and whether the design will pass their HOA. We answer both before the first nail. Since 2006, Sutton ADU Houston has built additions and ADUs that survive Greatwood’s architectural-review process because we do the neighborhood-specific homework most contractors skip.
Our crews have framed additions in Canyon Gate, Lakemont, and older sections near Crabb River Road. We know which streets require brick veneer aprons, which HOAs mandate 6:12 hip roofs, and which committees demand a drainage plan with the first submittal. That knowledge isn’t theoretical. It comes from standing in front of committees and hearing why plans get rejected. Miles Hartwell, who runs our Houston operations, reviews every Greatwood submittal packet personally before it goes out.
The 365-Day Done Right Promise covers defects in workmanship for one full calendar year from project completion. If something isn’t right, we make it right. No haggling, no fee, and if a repair is needed, the second visit is free. That’s the written guarantee we stamp on every Greatwood project.
We never promise a same-day build. We promise a locked price, a vetted crew, and a design that has a real chance of passing on the first submittal. For Greatwood homeowners, that’s worth more than speed.
Garage Addition Contractors in Greatwood
Garage Addition Contractors in Greatwood handle two different jobs: converting an attached two-car garage into finished living space, or building a new detached garage with a studio or in-law suite above it. Our past three garage conversions near Reading Junior High ran $65,000 – $120,000 for a full conversion with plumbing, HVAC, and drywall, while new detached garage-with-ADU builds start around $140,000 and climb from there depending on finish level. Both routes trigger HOA review, and both require a drainage plan in Greatwood’s heavy-rain climate.
The HOA Conversion Playbook
Greatwood deed restrictions treat garage conversions as a change to the home’s exterior appearance. Even if you keep the original garage door for a workshop conversion, the committee wants to see how the driveway gets repurposed and whether parking stays compliant. We submit a site plan showing the new driveway layout, the replacement exterior finish on the garage face, and a note on how stormwater flows off the converted slab.
What Our Crews Reinforce Here
Greatwood garages sit on slabs poured in the 1990s and early 2000s, and the soil under them has settled in patterns a simple inspection can miss. We check for slab cracks and moisture before we frame interior walls. If the slab isn’t right, we address it before any finish work goes in, because a cracked slab under a new bathroom is a one-year warranty claim waiting to happen.
Bathroom Addition Contractor in Greatwood
A Bathroom Addition Contractor in Greatwood usually builds one of two things: a first-floor full bath added near a living space, or an ensuite attached to a primary bedroom that never had one. First-floor bath additions in Greatwood typically run $28,000 – $48,000 depending on whether you need new plumbing runs, a wet-wall, or a slab penetration. Primary ensuite additions start around $45,000 and go up with glass surrounds, custom tile, and heated floors.
Plumbing Runs and Slab Work
Greatwood homes are mostly slab-on-grade, which means a new bathroom usually requires cutting through concrete to reach the drain line. We do that with a wet saw and a containment plan, not a jackhammer and a tarp. The HOA cares less about this interior work than the exterior changes, but if you’re adding a bathroom to a bump-out, the roofline and exterior finish still go through review.
Moisture Control on Bathroom Additions
Greatwood’s humidity is brutal on bathroom walls and ceilings. We spec exhaust fans sized to actual room volume, not the cheapest box at the supply house, and we use moisture-rated drywall throughout. A bathroom addition that isn’t ventilated properly here will show mildew on the ceiling within eighteen months. The 365-Day Done Right Promise covers that, but we’d rather build it right the first time.
Trusted Brands We Service in Greatwood
We work with Boxabl and Plant Prefab for pre-engineered units that can shrink Greatwood approval timelines because the engineering is already stamped. We also handle James Hardie exterior systems, which matter here because most Greatwood HOAs specifically approve Hardie plank and panel profiles to match the original 1990s brick-and-Hardie homes. If you’re considering a Tuff Shed studio conversion, we can frame out the interior and run electrical to code. We do not sell catalogs. We match the product line to what your street’s committee will actually approve.
Common Home Addition Contractor Problems We See in Greatwood Homes
- Stop-work orders from starting before HOA approval. Greatwood deed restrictions carry private enforcement, which means the HOA can halt construction on your own lot if the submittal wasn’t filed first. We file pre-application review three weeks before demo.
- The same plan approved on one street and rejected on the next. Canyon Gate requires a brick veneer apron on additions. Lakemont has different roofline preferences. One-size-fits-all plans fail in Greatwood. We check your specific block before you buy the design.
- Slab-on-grade builds that rot within a year. Greatwood’s heavy rains and humidity punish standard slab work. We use elevated 10-inch raised slabs with moisture-resistant materials and proper drainage so the addition isn’t mildewed before the first birthday.
- Submittal packets missing the drainage plan. Greatwood committees reject incomplete packs fast. We include finish samples, elevation drawings, and a drainage plan in every first filing, so the review clock runs on our schedule, not the committee’s whims.

FAQs About Home Addition Contractor in Greatwood
Typically three to six weeks, and we file the pre-application packet three weeks before demolition so that window overlaps our material ordering instead of delaying the build. Some committees meet monthly, which can stretch the clock. Call (940) 242-3207 and we’ll tell you exactly what your subdivision’s review cycle looks like.
Brick veneer to match the 1990s brick-and-Hardie homes, James Hardie plank and panel profiles, and 6:12 hip roofs to match the original two-story traditional style. Canyon Gate required a brick veneer apron on a recent 480-square-foot addition we built there. We know which streets require what, and we spec it before you buy materials.
No. It makes it stricter in practice because private deed restrictions vary block by block. There’s no city zoning office to appeal to. The HOA committee is the final word, and their rules change from one street to the next on rooflines and driveway widths. We handle the entire submittal and approval process so you don’t have to guess.
We use a 10-inch raised slab with a drainage plan filed in the first submittal, because Greatwood’s heavy rains punish slab-on-grade work. The drainage plan shows exactly where stormwater goes, and most committees want to see it before they’ll even review the elevations. It’s non-negotiable on our builds here.
Yes, if the garage face gets a finished exterior treatment the committee accepts and the parking plan stays compliant on paper. We’ve converted garages into in-law suites and studios near Reading Junior High, and the submittal packet includes the driveway layout and the new exterior finish. It passes when the committee sees you’ve thought through the same things they’re required to enforce. Call (940) 242-3207 for a free consultation on your garage.
